11 Claims.

This invention relates generally to window constructions and refers more particularly to improvements in windows of the type having a swinging ventilator.

5 It is one of the principal objects of the present invention to simplify, render more efficient and improve generally window constructions embodying a swinging ventilator by incorporating latch mechanism having the dual function of 10 securing the ventilator in its closed position and of supporting the ventilator on the frame for swinging movement relative to the latter.

Another advantageous feature of the present invention resides in the provision of latch mechanism having latching means associated with opposite ends of the ventilator and operable to clamp the latter ends at spaced points to the adjacent abutment flange of the window frame. This construction insures effectively securing the 20 ventilator in its closed position in the frame and serves to seal the contact between the ventilator and window frame.

A further advantageous feature of the present invention consists in the provision of a window construction equipped with latch mechanism of the above type wherein no part of this mechanism interferes with the application of screens or storm windows to the side of the frame opposite the side of the latter from which the ventilator swings. This feature is advantageous in that it eliminates the necessity of especially constructing the screens or storm windows to accommodate any part of the latch mechanism and, as a consequence, offers the possibility of appreciably reducing the cost of manufacture and installation of screens and storm windows.

In addition to the foregoing, the present invention contemplates latch mechanism of the character previously set forth capable of being 40 inexpensively manufactured, assembled, and installed. This feature, as well as the foregoing and other objects, will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawing, wherein:

Figure 1 is a perspective view of a window construction embodying latch mechanism constructed in accordance with this invention and 50 showing the ventilator in its open position;

v Figure 2 is a fragmentary elevational View of the inner side of the window;

Figure 3 is a sectional view taken substantially on the plane indicated by the line 3--3 of Figure 2; and

Figure 4 is a view similar to Figure 3, showing the parts in several different positions.

Referring now to the drawing, it will be noted that the window construction featured in the several views comprises a frame I and a Ven- 5 tilator II supported in the frame for swinging movement relative to the frame in an inward direction. The frame I0 is composed of vertical end bars I2 connected at the upper ends by means of a top bar I3 and at the lower ends by a sill bar I4. The ventilator I I is also provided with vertical end bars I5 connected together at the opposite ends by means of the top and bottom bars I6 and I 1, respectively. The top and end bars of the frame are provided with abutment flanges I8 extending into the window opening from the outer edges of the bars and adapted to be engaged by corresponding flanges I9 extending inwardly from the top and end ventilator bars, when the ventilator is in its 2 closed position. Upon reference to Figure 3, it will be noted that the sill bar I4 of the frame Ill is provided with a flange depending from the outer edge thereof and is offset inwardly from the cooperating bars to provide a space ZI between the flanges l8 on the end bars I2 of the frame and the opposite ends of the depending flange 20 on the sill bar I4 of the frame. This space is of sufflcient width to receive the flange 22 extending downwardly from the outer edge of the bottom bar of the ventilator and to prowide for the angular movement of the ventilator required to swing the same from the full line position shown in Figure 3 to the broken line position illustrated in Figure 4. It will be observed from Figure 3 that the bottom bar ll of the ventilator rests on the sill bar It of the frame and fulcrums about the latter when swung to its open position. The opposite end portions of the depending flange 22 cooperate with the abut- 4O ment flanges I8 on the end bars I2 of the frame Ill and with the adjacent portions of the de pending flange 20 to guide the ventilator as it is swung to its closed and open positions relative to the frame Ill.

With the foregoing construction, the usual hinge for the ventilator is eliminated and the ventilator is supported in its open position by means of the latch mechanism employed to secure the ventilator in the frame with the several vertical flanges aforesaid on the latter and ventilator in abutting relationship. The latch mechanism provided for the dual function briefly outlined above is designated in the several figures of the drawing by the reference character 23 and is duplicated at opposite ends of the ventilator. In this connection, attention is called to Figures 1 and 2 wherein the latch mechanism is shown as housed in the window frame between the opposite end bars l5 of the ventilator and the adjacent end bars I2 of the frame. Inasmuch as the latch mechanisms at both sides of the window are identical in construction and purpose, only one will be described in detail herein.

The latch mechanism 23 is provided with a supporting link 24 having an elongated slot 25 in the upper end for receiving a pivot pin extending laterally from the end bar l2 toward the ventilator I! and having a second elongated slot 21 adjacent the lower end for receiving a pivot pin 23 extending laterally from the end bar l5 of the ventilator toward the end bar l2 aforesaid of the frame. Both slots are elongated in the direction of length of the link E iand the slot 21 in the lower end of the link is formed with an enlargement 29 of sufficient dimension to freely receive a head 38 on the outer end of the pin 28. The diameter of the shank of the pin 28 is, of course, less than the narrow portion of the slot to afford the necessary sliding move ment, and the head is of greater diameter than the latter portion of the slot to maintain the link in assembled relation with the ventilator.

It will be observed from Figure 3 that the pin 28 is positioned on the end bar H) of the ventilator intermediate the ends of this bar and assumes a position at the upper end of the slot 2? in the closed position of the ventilator. The arrangement is such as to permit the ventilator to fulcrum about the inner edge of the bottom bar of the ventilator in a direction inwardly of the frame H1, and to permit the link 2-1 to swing inwardly about the pivot pin 25 at the upper end thereof. When the pin 28 on the side bar l5 of the ventilator abuts the lower extremity of the slot '2? in the link 24, further movement of the ventilator in an inward direction is prevented and the latter is supported by the link 2-! in its open position. The ventilator may be closed by merely swinging the upper end thereof back into the frame and, owing to the pin and slot connection with the link 24, the latter is automatically returned to its position in the frame where it is concealed from view.

It has previously been stated that the link also functions to latch the ventilator in its closed position and this is accomplished by merely shifting the link in a downward direction when returned to its inoperative position in the window frame llil. As shown in Figures 3 and 4, the outer edge of the lower end of the link 26 is inclined upwardly and outwardly, as at 32, and the opposite edge is inclined upwardly and inwardly to provide the cam surface 33. Upon reference to Figure 4, it will be noted that as the ventilator approaches its closed position in the frame ii], the inclined edge 32 of the link 24 cooperates with a projection 34, struck laterally outwardly from the lower end of the side bar E5 of the ventilator H, to raise the link relative to the side bar IS a sufficient distance to permit the lower end of the link to assume a position above and at the outer side of the projection when the ventilator is fully closed. The lower end of the ventilator may then be latched in place by merely forcibly moving the link 24 downwardly to wedge the cam surface 33 against the outer edge of the projection 34 and thereby effectively clamp the outer side of the ventilator to the abutment flanges IS on the frame.

In accordance with this invention, provision is also made for clamping the top portions of the ventilator to the window frame. This is accomplished by forming a recess M3 in the inner edge of the link 24 adjacent the upper end of the latter for receiving a pin M projecting laterally from the end bar E5 of the ventilator toward the adjacent end bar E2 of the window frame. The entrant end of the recess it] is so located with respect to the pin ll as to register with the latter when the link 24 is in its unlatched position or, in other Words, the entrant end of the recess is predeterminedly located to receive the pin 4| when the ventilator is swung from its open to its closed position in the frame. It will be observed from Figures 3 and l that the recess 18 is provided with an upwardly projecting extension 42 for receiving the pin 4i when the link 24 is moved downwardly to engage the came surface 33 at the lower end of the link with the projection 34, and the outer wall 33 of the extension 42 is inclined in a direction to wedge against the inner side of the pin M, as the link 26 is moved downwardly to its latched position. Inasmuch as the pin 4! is on the ventilator and the upper end of the link is supported on the frame, it follows that the upper portions of the ventilator are clamped to the frame at the same time that the lower portions of the ventilator are secured in place. It will also be apparent from the above that this simultaneous latching of the top and bottom portions of the ventilator to the frame, is effected by merely moving the link 24 downwardly after the ventilator has been moved to its closed position in the frame. Attention is directed at this time to the fact that the inner edge of the link 24 is inclined, as at 44, just above the entrant end of the recess 48 to engage the pin 4! during the final closing movement of the ventilator and insure registration of the recesses with the pin.

When it is desired to unlatch the ventilator from the frame, the link M is merely raised to the extent provided by the slot 25 at the upper end of the link and, in this uppermost position of the link, the lower end of the latter assumes a position above the projection 34 and the entrant end of the recess 50 registers with the pin ll. As shown in the several figures, manipulation of the link E to effect both the latching and unlatching functions is accomplished from the inner side of the window by a projection 45 extending inwardly from the link between the adjacent end bars of the frame and ventilator. In the present instance, the projection 25 is associated with the lower end of the link 2 5 just above the cam surface 33 where it may be conveniently reached by the operator for manipulaion.

Thus, from the foregoing, it will be noted that I have provided a relatively simple, inexpensive window construction having a swinging ventilator and having latch mechanism effective to hingedly support the ventilator on the window frame. It will also be noted that the latch mechanism is extremely simple in construction and operation, and acts on each end of the ventilator at spaced points to effectively clamp the top and bottom portions of the ventilator to the frame.
